I would not want a camper without a generator for exactly the reasons you mentioned. I have only stayed a few places where I needed to run the A/C at night, but I have had plenty of evenings when the camper was hot from sitting in the sun during the day. Without an A/C it can take hours and hours to cool off. In a few cases, it was hot but campground rules prohibited use of the generator. That is no big deal with a TC. I leave, find an isolated spot outside of the campground and run the A/C for an hour or so.
I would get rid of the propane unit. Perhaps it has some resale value. They just chew through the propane. It is easy to carry a few gallons of gas and to replenish at gas stations anywhere. Refilling propane can be an issue in remote areas.
I actually rarely use my generator, but it is a necessity for those times when it is needed for cooling or charging batteries. I even start mine up to use a hair dryer when defrosting the fridge.
